low/high aux alarm

[John Mcpartland]

this alarm came on not last time out but the time before. I thought it was because the batteries were low so we went back in and put the batteries on the chargers and fully charged them. we went out yesterday and the alarm is still there. Both batteries are fully charged right now, 12.7 and 12.78V, and when I turn on the house battery and press a conext button to turn it on the alarm comes on right away. I swapped both batteries and it still does it. the little black wire is connected and tight. Any other trouble shooting tips?

anybody have any troubleshooting tips for a low aux battery alarm. batteries are both fully charged (12.7v) and the dvsr seems to be working correct. I pit my charger on one battery yesterday and after about 1 hour the red light came on saying the other battery is charging. I started both engines and I am getting 13+V while idling. I've had the boat out twice with this alarm and everything works how its supposed to. the conext screen says 0.0 aux voltage. I also swapped the house and start battery with the same results. any help is appreciated.

I am having the same issues on a ‘17 242x. I have checked all of the connections, battery, etc. Any ideas what else to look at?
